Diagnosis. — Sharks of moderate size (reaching at least 905 mm. 

 t.l.) distinguished from other carcharinid genera by the following 

 combination of characters: origin of second dorsal fin ranges from 

 over, and just in advance of, anal axil to slightly behind anal axil 

 (usually); cusps of teeth smooth and obliquely directed rearward; 

 labial furrow on upper jaw poorly developed, usually shorter than
